Someone's killing Treadstone agents and Jason Bourne may be next on the list in this latest electrifying entry in Robert Ludlum’s #1 New York Times bestselling series.

From the glacial waters of Alaska to a sexy nightclub in the Bahamas, Treadstone agents are being hunted down and murdered. Someone high up in the U.S. government will stop at nothing to cover up a secret Treadstone mission from the past known as Defiance.

With a team of killers hot on his trail, Jason Bourne chases the mystery of Defiance around the world. But as he closes in on the shocking truth, Bourne realizes that one man holds the key—his archenemy, the assassin known as Lennon.  The Russian hitman has been at the heart of Defiance from the very beginning, and his next target will put Bourne —and the woman he loves—in the cross-hairs.

As Bourne races to stop the ruthless conspiracy behind Defiance, he must come face to face with Lennon one last time—and the stage is set for a final violent showdown.
